Gryphon's Tea. It's at 4127 Butler Street and it took us 5-10 minutes to walk there from the restaurant.
Gryphon mentioned that eventually there will be small tea tastings/classes, which sounds interesting. The shop also sells herbs and spices - the list is just as long as the tea list!
We are very happy to have another tea shop in Pittsburgh. We love Margaret's in Squirrel Hill and now there is Gryphon's in Lawrenceville. They sell different teas, which is nice. We also still enjoy a relaxing cup at Te Cafe while catching up on our reading and there is another tea shop across Murray Avenue from Te Cafe called Dobra Tea.
